Hi I deployed my nextjs 13 app with app router feature into google cloud. Everything is packed into docker and deployed properly, but I receive such an error:

Error: > Couldn't find any pages or app directory. Please create one under the project root

Anybody knows what is going on with that ? or Google Cloud is not supporting app router yet ?

Docker is working fine locally atm and there is no issue with that.
